FLIER CONSTRUCTION Filed May 29, 1935 Patented July 10, 1934 UNITEDSTATES PATENT OFFICE 13 Claims.

My invention relates to improvements in flier blocks and moreparticularly to an arrangement whereby the flier wires are attached to aflier block.

In my applications, Serial Numbers 554,312, filed July 31, 1931 and657,691, filed Feb. 20, 1933, there is disclosed a pre-formed flierwire, securing means therefor, and an improved flier block having aremovable foot. The present invention is an improvement over thedisclosures of the above mentioned applications and comprises a flierblock formed with a tapered peripheral groove, the block being slottedand adapted to receive a separate pre-formed wire loop, the ends ofwhich seat in the block and securely lock the flier wire in theoperative position. Means are also provided for locking the block to abobbin or its associated spindle.

An object of my invention is to provide an improved flier block whereinthe flier wire is securely fastened to the flier block by means of aseparate locking wire.

Another object of my invention is to provide a flier block having atapered peripheral groove formed therein whereby the flier wire iswedged against the surfaces of the groove when the wire locking means isplaced in the operative position on the block.

Yet another object of my invention is to provide a novel flier blockstructure having mutually interlocking means adapted to maintain theflier wire on the block and additional means to attach the block to abobbin.

Still another object of my invention is to provide an improved flierblock assembly wherein the locking means for the flier wire also acts asa thread tensioning and guiding means.

A still further object of my invention is to provide an improved flierblock which is of general application in connection with various typesof flier wires and bobbins.

With these and other objects in view, which may be incident to myimprovements, the invention consists in the parts and combinations to behereinafterset forth and claimed, with the understanding that theseveral necessary elements, comprising my invention, may be varied inconstruction, proportions and arrangement, without departing from thespirit and scope of the appended claims.

In order to make my invention more clearly understood, I have shown inthe accompanying drawing means for carrying the same into practicaleffect, without limiting the improvements in their useful applicationsto the particular constructions, which for the purpose of explanation,have been made the subject of illustration.

In the drawing, like numerals refer to similar parts throughout theseveral views, of which Figure 1 is an elevational view partly invertical section of a bobbin provided with a flier block having a flierwire and locking means therefor.

Fig. 2 is an elevational view partly in vertical section of a bobbin andassociated retaining bushing, showing a modification of the improvedflier block.

Fig. 3 is a perspective view of an improved preformed flier wire.

Fig. 4 is an enlarged sectional view along line 4-4 of Fig. 5; and

Fig. 5 is a plan view of Fig. 1, with the flier fastening means removed.

Referring to the drawing and more particularly to Fig. 1, there isdisclosed a bobbin 1, mounted upon a spindle 2 having a tapered uppersection 3' adapted to support a freely rotatable flier block designatedgenerally by numeral 4. The flier block is centrally apertured and thebody portion thereof is provided with flanges 5 and 6, defining aperipheral flier wire receiving groove 7. It will be noted that theupper flange 5 is under cut as at 8, and that the upper surface of lowerflange 6 is horizontal. The purpose of this arrangement is to enable aflier wire to wedgingly engage with the surfaces of the flanges when itis attached to the block as will be described more fully hereinafter.

Seated in the peripheral groove 7 is a flier wire having arms 9 withvertical portions 10 provided with eyelets 11. As more clearly shown inFig. 3, the flier wire is also provided with a central block engagingsection 12 and ofiset portions 13 adjacent said section.

Referring to Figs. 4 and 5, it will be seen that the block is furtherprovided with a slot 14 extending across the top thereof and of a depthgreater than the width of the groove '7. As shown in Fig. 5, the slotextends into the bottom flange 6 forming a slotted portion or recess 15.In line with the slot 14 and on either side of the central aperture ofthe block, openings 16 are formed in the flange 6, adapted to receivethe flier Wire locking means.

The improved locking means comprises a wire loop 7 having offsetportions 18-19, horizontal portions 20 and vertical legs 21. The legs 21are adapted to seat in the openings 16 with the horizontal portions 20resting in the recessed portion 15 formed in the bottom flange. It willbe noted that the offset portions 18 of the loop extend a short distanceinto the slotted portion of the upper flange and contact therewith inorder to prevent tilting of the loop when it is in the operativeposition.

In assembling the device, wire loop 17 is placed in position on theblock with legs 21 seated in the openings 16. This is accomplished byfirst inserting a leg in one of the openings and pushing the other endof the wire along the length of the slot 14 until the other leg can beseated in its corresponding opening. When the loop is in this positionthe horizontal portions 20 are in the recesses 15, the upper surfaces ofportions 20 being flush with the surface of flange 6. The flier wire isthen applied to the block by bending it in the form of a loop andslipping the looped portion down over the top fiange 5. It will beunderstood that offset portions 18 formed in the loop 17 can be movedout of contact with the slot 14 to give suflicient clearance for theflier wire to seat in the groove. After the central block engagingsection of the flier wire is seated in the groove 7, the arms 9 of thewire are bent outwardly so that they are in line with the slottedportion of the block.

With the above described arrangement, the flier wire is securelyattached to the block during normal operation of the block, however, itcan be readily detached for the purpose of replacing it with anotherwire or f or other reasons. Since the flier wire overlaps the horizontalportions 20 of the wire loop 17, it will be appreciated that any upwardpull or thrust on the loop Will tend to wedge the flier wire intotighter engagement with the groove. By undercutting the upper flange 5,flier wires of various diameters can be accommodated and throughout therange of diameters for which the present block is designed, the wireswill be tightly held in the groove and in contact with the innersurfaces of the flanges.

It will be noted that the offset portions 13 of the flier wire are inmutual engagement with offset portions 19 of the loop 17, when the flierwire is seated in the wire receiving groove, thus preventing movement ofthe flier wire with respect to the block.

Since ofiset portions 18 of the loop extend into the slot formed inflange 5, the loop cannot move laterally and the flier wire is retainedin the groove due to its mutual interlocking with portions of the loop.

Referring to Fig. 2, there is disclosed a bobbin 21 mounted upon aspindle 22 having an upper section 23 of uniform diameter, adapted tosupport a freely rotatable flier block 4. The bobbin is also providedwith a bushing 24 having an inwardly projecting flanged portion 25. Theblock 4 is similar in construction to the arrangement shown in Fig. 1,however, differs from it in that it is provided with an additionalperipheral groove 26 adapted to receive a removable foot member 27. Thisarrangement is intended for use with bobbins having end bushings andenables the block to be locked to the bobbin during normal operation ofthe device. The foot 27, which may be formed of wire or other suitablematerial, is eccentric with respect to the body of the block andprojects inwardly beyond the edge of the flanged portion 25 of thebushing. In this manner, the block is securely attached to the bobbinand at the same time is free to rotate about the spindle.

It is sometimes desirable to provide thread guiding and tensioning meansin addition to that afiorded by the flier wire. In the presentarrangement, I have incorporated a thread tensioning and guiding devicewith the flier wire locking means comprising a wire loop 28 formed withan eyelet 29 of suitable configuration. By means of this construction,additional tensioning is provided for the thread, which may be readilysubstituted for the flier wire fastening means used in connection withthe block shown in Fig. 1.

It will now be appreciated that I have provided an improved flier blockassembly, including flier wire locking means, which is of generalapplication with bobbins and spindles or" various types. If thearrangement shown in Fig. 1 is used, the block is retained on thespindle by means of a mill nut 30. For bobbins having an end bushing,the block shown in Fig. 2 is used.

While I have shown and described the preferred embodiment of myinvention, I wish it to be understcod that I do not confine myself tothe precise details of construction herein set forth, by way ofillustrations, as it is apparent that many changes and variations may bemade therein, by those skilled in the art, without departing from thespirit of the invention, or exceeding the scope of the appended claims.
